We look at the division of 51253 by 77 
Let's see how many times 77 fits into 51253.

Let's proceed to step 1:
The number 77 fits into 5 0 times, leaving a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Append the next digit (1) from the dividend to 5 and continue with: 51 / 77

Step 2:
The number 77 fits into 51 0 times, leaving a remainder of 51.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 51 to get 51.
Fetch the next digit (2) from the dividend, attach it to 51 and continue: 512 / 77

Going ahead to step 3:
77 goes into 512 6 times with a remainder of 50.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
The remainder is 50 after subtracting 462 from 512.
Bring next digit (5) of the dividend behind the 50 and repeat the process: 505 / 77

Step 4:
When dividing 505 by 77, we get 6 with a remainder of 43.
Record the quotient 6 as the next digit in the result. 
Result so far: 66.0
If we take 462 away from 505, we end up with 43.
Fetch the next digit (3) from the dividend, attach it to 43 and continue: 433 / 77

Moving on to step 5:
If we divide 433 by 77, we get 5 and a remainder of 48.
Write down 5 as next digit of the result. 
Result so far: 665.0
Deduct 385 from 433 and we're left with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

On to step 6:
77 goes into 480 6 times with a remainder of 18.
The number 6 becomes the next digit in our result. 
Result so far: 665.6
Subtracting 462 from 480 leaves us with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Step 7:
The number 77 fits into 180 2 times, leaving a remainder of 26.
The next digit of our result is 2. 
Result so far: 665.62
If we take 154 away from 180, we end up with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Going ahead to step 8:
If we divide 260 by 77, we get 3 and a remainder of 29.
Put 3 as the next digit of the answer. 
Result so far: 665.623
Subtract 231 from 260 to get 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Going ahead to step 9:
If we divide 290 by 77, we get 3 and a remainder of 59.
The next digit of our result is 3. 
Result so far: 665.6233
Subtract 231 from 290 to get 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

The final outcome is 665.6233, with a leftover of 0.00059.
